I have a few bad sectors. When I'm trying to boot up my computer it will tell me to run scandisk so when I run scan disk it will say that an error occured preventing scandisk from correcting an error. Does anyone know any programs I can download to correct bad sectors?

PS - I hate this old crappy computer. I really do need to get my dell a new power supply -_-.

Geeze, if sectors are bad, how can software fix hardware?

If you have DISKEDIT on a floppy and are DOS savvy:

Clusters marked as bad are found in the FAT as followes:
FAT12 7 FF
DISKEDIT: DISKEDIT C: /w start in write mode
Alt+F1 first fat
Ctrl+S search dialog
TAB enter hex area
F7 FF FF 0F Ctrl+G to continue search


You can force ScanDisk for Windows to retest bad clusters by modifying the value
for the following registry key:

Applets\Check Drive\Settings

This registry key will exist only if ScanDisk for Windows has already been run at least once. To have ScanDisk test clusters that have been marked as bad, modify the Settings value so that the last two digits are "04." For example, if the current value for Settings is:
B1 03 40 00

change it to read:
B1 03 40 04

Once you modify the value for Settings, ScanDisk for Windows will retest any
clusters marked as bad (one time).


Or if you just wanna stop the scan every boot modify this line in MSDOS.SYS:

:thumbsup: Tick box in scandisk to auto correct errors,which it doesn't- it will overwrite
and mark them as unusable.Try running scandisk in "safe" mode to avoid the error message.Disk Dr from nortons is good,but not THAT good.Not sure if scandisk
corrects defects but they don't show up twice-run it repeatedly until it's clear &
doesn't report bad sectors anymore.

Check the hard drive manufacturers site for their diagnostic software. They have some really good utilities that will let you know exactly what is going on. Yes, software can repair hardware in this case and many others. Thats why you flash a Bios or other firmware.
